Y My invention relates to fueling systems and has for its object to provide a means for raising the fuel from the tank from which it may be drawn to the carburetor. Y

A further object is` to provide a booster for use in drawing the fuel from the tank, which booster will increase the suction of either the carburetor, the pump, or the vacuum tank, aiding in drawing the fuel from the tank.

rllhese objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout the severalV tioned to show the operating portions there-V of. Figure V2 is a plan view of thev booster with the lead pipe removed therefrom and the booster removed fromr the tank.

Vcasting rests when` it is screwed down into the hole 1. A screen 6 is then secured around the casting 2 having the top and bottom ends secured to the flanges 5. of the said casting 2, I place an upright air pipe 7 which pipe has its top end secured in a` cylindrical socket 8. Thesocket 8 is secured through a threaded hole in the top side of the tank A and an elbow 9 is screwed onto the top free end of the socket 8; v An air pipe 10 is screwed. into the end ofthe elbow 9 and said pipe leads to any desired source of air supply preferably to'an air filter or cleaner which may be pre-heated by the heat of the placed inthe bore 13 as to leave anY annular In the top endV 4'ekhaustof engine. ".Thebooster l,11 is then placed downf into; the casting 2, and" having 44ou'twardf radially extendingV bosses 18 19, and

2O Whichhold the booster spac'eequally from fthe-walls Iofthe casting2 and a portjlvG` is pros tending down from the top end thereof and bored?) is formed-in the bottom endof the booster intowhich borethe endlofthebore`12 Y terminates,l with the 'body of the, kcasting `2 which surrounds' the'eXtreme end ofthe bore,

formed in a frusto-conical p,ortion'15a,;whi`ch po-rtion,"'extends down i-nto 'the bore 13. A

plug 14 is then pressed into the end of the bore 13 and the top end of the plug is also formed frusto-conical similar to the end pory tion of the bore 12. A bore 14a is formed in the plug -14 having thetlower end curved oute wardly and having the upper portion thereof with the walls parallel. The plug 14 is so space 15 between the upper end of the plug and the end of the casting within the bore, and the port 16 is in direct communication and bored into the space 15. A pipe 21 is secured in the top end of the booster 11 and an elbow 22 and pipe 23 connect the booster and pipe 21 with the carburetion vacuum tank or pump as used. Y

The operation of my device isas follows: Air is sucked through the pipe 23, the elbow 22 and the pipe 21 by the carburetor, the vacuum tank, or the pump, or other fueling sys-V tem and as this air isdrawn therethrough it is drawnup through the tapered boreV 12, and the bore 14a of the plug 14, and air is drawn through the casting 2,'the pipe 7 and the pipe 10, and the fuel is drawnfthrough the ports 16 and 17 into the annular space15 whereV it is mixed with the air and drawn up through the Vpipe 21 in the form of a vapor. Should vthe engine be stopped the fuel will enter Aformed 'throulgh thefcasting 2"' to 'provide Vso esl seek the level of the fuel in the tank, and for starting the motor the suction through the pipe 21 Will draw raw fuel in the unmixed stage through the said pipe until such time as all fuel is drawn from the pipe?, the casting 2, the chamber 4f and the opening 15 and at such time the suction therein .will then draw air through the same source to the opening 15 Where it Will then be mixed With the raw fuel to form the vapor. `This aids. the starting of the motor giving a rawfuel instead of a vapor through the pipe 23.

Having thus described my inventionfI desire to secure by Letters Patent and claim:

A booster for use With fuel systems consisting of a'sereen. casting seeuredin the bottom .of atanl; a: screen around `said casting; a 'port connecting' the exterior of 'said casting vWith a booster l member Icarried therein; .a taperedihole through 4said booster; ai bore in the' bottom end oir'` said booster a plug in-said hole having Aa Y bore therethrough said. plug being spaced fromtheend of thetapered hole; alport connecting said space With the 1 port through the casting; a pipe to allow air Vto,be drawn down into said casting. and up through said booster; and a pipe connecting the top end ofthe tapered hole in said booster with means of Carburetting the-fuel.

Intestimony whereof he has a-Pxed his signature.
